Definitions

  • the present invention relates to a device and method for reducing the consumption of urea and/or hygroscopic chemical substances in paste materials for printing cotton and viscose fabrics.
  • Prior steaming chambers are affected by several drawbacks, the main of which is that they require that comparatively great amounts of urea be used, with a consequent great pollution of the used water.
  • This urea is required in order to absorb water present in the processing steam, so as to cause the cellulose fibres to be swollen.
  • urea facilitates the absorption of the dye material as well as its chemical reaction with the fibres to be dyed.
  • This reaction will cause further steam to condensate, so as to enhance the moisture contents of the printed fabric, thereby promoting the above mentioned setting process.
  • ammonia is evolved which pollutes air to which steam is discharged or the water used in a fabric washing step following the steam setting step thereof.
  • the aim of the present invention is to overcome the above mentioned drawbacks, by providing a device and for reducing the urea and/or chemical substance consumption in cotton, viscose and the like fabric printing paste material, affording the possibility of moistening, in a very even and constant manner, the fabric, before the steaming step thereof, so as to bring the fabric to its natural moisture contents value, before the printing step or, preferably, so as to bring said fabric to higher moisture contents values.
  • a main object of the present invention is to provide such a device allowing to print fabric materials in a very satisfactory manner, owing to a very accurate metering of the processing steam.
  • Another object of the present invention is to provide such a device which can be easily applied to available fabric steaming chambers and which, moreover, if desired, can also be used as an independent unit for reducing the hygroscopic substance contents of fabric printing paste materials.
  • Yet another object of the present invention is to provide such a device which can be operated in a continuous manner, without modifying the conventional operation characteristics of available fabric printing systems and which, moreover, is such as to greatly reduce the pollution problems.
  • Yet another object of the present invention is to provide such a device which can be easily made starting from easily commercially available elements and materials and which, moreover, is very competitive from a mere economic standpoint.
  • a device for reducing the consumption of urea and/or hygroscopic chemical substances in paste materials for printing cotton and viscose fabrics characterized in that said device comprises, upstream of a steaming chamber, a pre-moistening chamber into which there are introduced saturated steam and, in a continuous manner, a printed fabric material to be processed.
  • the fabric material is caused to pass, for at least a length thereof, through the pre-moistening chamber and, for at least a length thereof, through environment air, in order to cool it, and then being immediately introduced again into the steaming chamber.
  • FIG. 1 illustrates a pre-moistening device which can be directly applied to a steaming chamber
  • FIG. 2 illustrates the pre-moistening device applied to a steaming chamber having an open bottom
  • FIG. 3 illustrates the pre-moistening device applied to a steaming chamber having a closed bottom
  • FIG. 4 illustrates the pre-moistening device applied to a steaming chamber of a commercially available type
  • FIG. 5 illustrates a pre-moistening chamber, which can be used as an independent unit, in combination with prior steaming chambers;
  • FIGS. 6, 7 and 8 illustrate the pre-moistening chamber connected to several different steaming chambers.
  • the device for reducing the consumption of urea and/or hygroscopic chemical substances in paste materials for printing cotton and viscose fabrics comprises a pre-moistening device, generally indicated at the reference number 10, including a hood framework 11, provided to be affixed at the inlet of a steaming chamber, indicated at the reference number 12.
  • hood framework 11 communicates with the steaming chamber 12, thereby steam will be directly supplied by this chamber.
  • a roller 15 for spreading the printed fabric material, indicated at the reference number 20, and on which the fabric material is entrained, with an upward length 20a, inside the pre-moistening chamber, and a subsequent downwardly directed length 20b exiting the pre-moistening chamber, so that the fabric material will be subjected to a steaming step for a preset time, followed by a further step in which the fabric material is held in environment air.
  • the hood framework which is opened at its bottom, is fully occupied by the saturated steam, supplied by the steaming chamber 12.
  • the steam Since the steam has a density smaller than the density of air, it will tend to occupy all the pre-moistening chamber, so as to eject therefrom air present therein through the opening provided through the bottom of the pre-moistening device.
  • These channels are held under a negative pressure condition so as to continuously eject therefrom the excess steam, which would tend to exit the pre-moistening chamber.
  • a photo-cell system indicated at the reference number 23, which is specifically designed to adjust the length of the fabric lap exiting the pre-moistening chamber and which will be successively introduced again, through a transmission roller 25, into the pre-moistening chamber, before being introduced into the steaming chamber.
  • the fabric will be held in the pre-moistening chamber for a sufficient time to recover its natural moisture, lost during the previous printing process, and even to increase the amount of said moisture.
  • the fabric After having passed through the steam of the pre-moistening device, the fabric is removed from the hood framework and then it will follow its path through environment air, for a preset time period, during which the fabric will be cooled down.
  • the fabric can be introduced into a conventional steaming chamber, where it will be started the process for setting the dye material to the fabric fibres, so as to allow the possibility of using reduced amounts of urea and/or hygroscopic chemical substances.
  • the pre-moistening device can comprise a pre-moistening chamber 30, independent from the steaming chamber, and including a framework 31, open at the bottom thereof, with a steam source 32 and a suction unit 33.
  • a heating coil 35 can be provided on the top of this chamber.
  • the fabric still indicated at the reference number 20, will be supplied in a lap configuration, with length thereof conveyed inside the pre-moistening chamber, followed by a path through environment air, so as to provide a proper cooling of the fabric, and facilitate the condensation of the steam as the fabric is introduced again into a steam environment.
  • the pre-moistening chamber 30 can also be applied to commercially available steaming chambers, as it is schematically shown in FIGS. 6, 7 and 8.
  • the apparatus comprises either one or more perforated lance elements, designed for injecting steam on the fabric, in a continuous and even manner, before supplying the fabric into the steaming chamber.
  • the used materials provided that they are compatible to the intended use, as well as the contingent shape and size can be any, according to requirements.
